Cable Error
Messages
Low Voltage Errors
Low voltage errors identify errors in the cable wire pattern.
SHORT
The tester displays short if it senses an interconnection that should not exist in the cable.
There are two kinds of short errors.
Some shorts are between nets that exist in the net list.
For example, this kind of short would be detailed like this.
If the user preference Fault Location
were turned on, the short above would
be displayed like this.
Asterisks are added to the pins in the net
that are closest to the short. The tester
does this using resistance measurements.
Other shorts are not connected to nets in the net list.
For example, this kind of short would be detailed like this.
A NET NC SHORT indicates a short exists
between two N
o Connect pins, or between
a net and a N
o Connect pin.
Shorts are caused by:

Defects in the cable such as frayed wire strains, bridging solder joints, or very
conductive contaminates between exposed connections.

The LV Insulation Resistance Setting is set above the actual resistance of the insulation
between nets; therefore, nets that are leaking to each other show up as shorts.
